10. A Personal Emergency Response System (PERS) comprising: a PERS call center including an electronic call routing device; a machine-to-machine (M2M) server; and a wearable mobile call device as set forth in claim 1 .

11. A wearable mobile call device for use in conjunction with a Personal Emergency Response System (PERS), the wearable mobile call device comprising: a cellular radio configured for voice communication and data transmission; a call button; one or more locator services configured to acquire a current location of the wearable mobile call device, which is configured to be worn by a user; a built-in speaker and microphone; and an electronic processor programmed to: send a machine-to-machine (M2M) message from the cellular radio to a PERS call center via a M2M server wherein the M2M message includes at least PERS subscriber or wearable mobile call device identification information and current location information acquired by the one or more locator services; and after sending the M2M message, receive and conduct a voice call originating from the PERS call center using the cellular radio and the built-in speaker and microphone.

12. The wearable mobile call device of claim 11 wherein the wearable mobile call device is not programmed to originate a voice call to the PERS call center.

13. The wearable mobile call device of claim 11 wherein the wearable mobile call device includes no other user control besides the call button.

14. The wearable mobile call device of claim 11 wherein the wearable mobile call device is further programmed to initiate a voice call to a Public Safety Answering Point (PSAP).

15. The wearable mobile call device of claim 14 wherein after initiating the voice call to the PSAP the wearable mobile call device is further programmed to conduct a conference voice call between the PSAP and the PERS call center.

16. The wearable mobile call device of claim 11 wherein: the wearable mobile call device is configured to store one or more emergency contact M2M-compliant mobile device addresses; and the wearable mobile call device is programmed to send the M2M message addressed to the PERS call center and to each emergency contact M2M-compliant mobile device address stored in the wearable mobile call device.

17. The wearable mobile call device of claim 11 wherein the wearable mobile call device is programmed to send the M2M message as an Extensible Messaging and Presence Protocol (XMPP) message from the cellular radio to the PERS call center via the M2M server.

18. A Personal Emergency Response System (PERS) comprising: a PERS call center including an electronic call routing device; an Extensible Messaging and Presence Protocol (XMPP) server; and a wearable mobile call device as set forth in claim 11 wherein the wearable mobile call device is programmed to send the M2M message in XMPP from the cellular radio to the PERS call center via the XMPP server.

19. A method of placing an emergency call using a Personal Emergency Response System (PERS), the method comprising: detecting activation of a mobile help button of a wearable call device and transmitting an Extensible Messaging and Presence Protocol (XMPP) message from the mobile help button to a PERS call center via an XMPP server; and after sending the XMPP message, receiving and conducting a voice call originating from the PERS call center using the mobile help button.

20. The method of claim 19 further comprising: keeping cellular communication of the mobile help button off; turning on the cellular communication of the mobile help button in response to detecting activation of the mobile help button and performing the transmitting and the receiving and conducting with the turned on cellular communication.
